Group N silicone turbo inlet! Super JDM part extraordinaire?

Hey....! Welcome back to another #modmonday where I give you my take on an installed part on one of my Subaru's. Today we will get some first impressions and thoughts on my Group N turbo inlet from Subaru for Turbo EJ motors. 

Group N and two Perrin turbo inlets sit on a stoop… I don’t know the rest of the joke.

When you are looking to purchase a turbo inlet for your turbo Subaru there are countless options but what is right for you? After sifting through many I decided that Perrin seemed to have a good reputation, build quality and dyno info. For 6 years it had performed very well but there were a couple concerning areas that put me back on the market for a new turbo inlet. 

These were starting to bug me on the Perrin inlet, Wasn’t easy to tell if it had gone through.

What would be the best replacement for a good part, a great one! This is where a late night search located this Group N turbo inlet... I had always been a huge fan of the S203-206 cars and wanted my car to be a bit closer to those.

 The design is simple yet effective, it is larger like most aftermarket designs, but fitment is much better. Where the Perrin inlet loved to push on everything around it like the manifold, evap hoses, fuel lines and power steering pump. The Group N unit is large but not obstructing and pushing on everything. The Perrin unit started to rub a hole in it's self on the manifold. 

Since the Japanese STi doesn’t have a purge solenoid we have to go ahead and cap this line off.

Moving the Evap solenoid around to get to the blue T and cap that off as well.

Overall the quality is top notch and that is one of my favorite differences. The metal fittings it comes with are excellent and give it a nice touch. I bought mine used so it was unfortunately missing one, I am sure I can find a replacement to complete the look. 

Everything you need in an inlet and nothing you don’t!

The power band remains unchanged as far as my butt dyno is concerned. My protune has remained unchanged and it appears that the engine is running better at idle and part throttle. The only downside is the price, finding one new will run your around $1k, the used market is a bit more reasonable for half or less, depending on the condition.

Enjoying it’s happy new home within the engine bay. Tight fit but much easier to get in and out than the Perrin it replaced.
